Brook Drumm has created a series of videos that show the assembly process for the basic printrbot. As he produces additional videos and any for the printrbot LC and printrbot+ they can be added here too. Note that once you link to YouTube the videos will chain into a continuous running show. Well, at least the first 15 do this!

Brook's YouTube channel is here:

This video continues with tightening and aligning the base assembly.

(Out of date - see You want to assemble the X-axis, Video 10/11, before this step so you know how wide to make the base.

X axis carriage, beginning with the end stop mounting. Note design improvements and retrofitting original design.

I think this is wrong orderwise. I would attached the coupler to the x-motor, such that the geared part is furthest away from the body. Then I would mount the x-motor through the large hole, using three allen screws. Then mount the x-stop switch.
